Hi all, I wonder which is the correct key to create/recreate an additional OSD with 12.2.5. Following http://docs.ceph.com/docs/master/rados/operations/bluestore-migration/#convert-existing-osds, I took one of my old OSD out of the cluster, but failed subsequently recreating it as a BlueStor OSD. I tried "ceph-volume" at first, now got one step further using "ceph-disk" with "ceph-disk prepare --bluestore /dev/sdh", which completed, I assume successfully. However, "ceph-disk activate" fails with basically the same error as "ceph-volume" before, ~# ceph-disk activate /dev/sdh1 command_with_stdin: 2018-07-06 16:23:18.677429 7f905de45700 0 librados: client.bootstrap-osd authentication error (1) Operation not permitted [errno 1] error connecting to the cluster Now this test cluster was created under Jewel, where I created OSDs by "ceph-osd -i $ID --mkfs --mkkey --osd-uuid $UUID" and "ceph auth add osd.#{ID} osd 'allow *' mon 'allow profile osd' -i /var/lib/ceph/osd/ceph-#{ID}/keyring" This did not produce any "/var/lib/ceph/bootstrap-osd/ceph.keyring", but I found them on my mon hosts. "ceph-volume" and "ceph-disk" go looking for that file, so I put it there, to no avail. Btw, the target server has still several "up" and "in" OSDs running, so this is not a question of network or general authentication issues.
